Recipe evidence check

Registry change: scoped to recipes that reference a changed component
entry in recipes/registry.yaml (not every leaf).

Other affected recipes without evidence yet: 2

These recipes are affected by this PR but carry no committed evidence pointer, so there is
nothing to verify. This is expected — evidence is hardware-gated and added over time.

  • h100-gke-cos-training-slurm
  • h100-kind-training-slurm

This gate is warning-only and never blocks merge. See ADR-007 for the trust model.

📝 Walkthrough

Walkthrough

Updates Slinky Topograph configuration to use top-level provider, engine, service, nodeObserver, and nodeDataBroker settings. Updates overlays and registry scheduling paths. Changes the Kind overlay to use the small-tree.yaml fixture and validate its three-switch topology. Updates documentation and chart or image references from version 0.5.0 to 1.0.0.

provider.name is set, or revise the preceding documentation to explicitly state
slinky as the default. Keep the provider and engine validation guidance

Approving. Verified the v1.0.0 migration against upstream at the tag: the test provider now enforces a bare filename (pkg/providers/test/test.go, filepath.Base(p.ModelFileName) != p.ModelFileName), so the mounted kind-test-model.yaml ConfigMap genuinely cannot work anymore and the built-in tests/models/small-tree.yaml is a reasonable replacement. The asserted topology.conf matches that fixture exactly, and the global.* → top-level and node-observer/node-data-brokernodeObserver/nodeDataBroker renames line up with the v1.0.0 chart.

One nit, non-blocking.

The Kind leaf no longer validates effective topology. The test provider returns the fixture's instance map, and the Slinky engine short-circuits on a non-empty map (pkg/engines/slinky/engine.go, ResolveComputeInstances returns instances unchanged in both the static and useDynamicNodes branches), so the emitted topology.conf names I21I36 rather than the leaf's actual one-replica worker slinky-0. The previous fixture referenced slinky-0 deliberately so the check exercised the pod-resolution path end to end.

This is test fidelity, not runtime correctness — no real cluster uses provider.name: test, and Slurm treats unknown nodes in topology.conf as warnings rather than a load failure, so the Kind CUJ still comes up. Suggested follow-up rather than a change request:

  • Reword the comment above healthCheckAsserts so it says the assertion pins the fixture's shape, not that it validates the real Slurm worker. As written ("makes the exact topology.conf content assertable") a future reader may assume the coverage that was there in v0.5.0.
  • Track restoring effective-topology coverage separately. The *-sim providers still accept a path-bearing modelFileName (pkg/providers/providers_sim.go + the per-provider provider_sim.go loaders call models.NewModelFromFile with no bare-filename check), so a mounted model mapped to slinky-0 remains reachable that way — with the caveat that NewBaseSimProvider expects provider-shaped instance IDs, so it is not a drop-in swap.

The commit is signed (SSH) and has the DCO sign-off — it shows as unverified with reason unknown_key, meaning GitHub can't match the signature to a signing key on your account.

Usual cause: the SSH key is registered as an Authentication key only. Adding it under Settings → SSH and GPG keys → New SSH key with Key type: Signing Key fixes it. GitHub re-evaluates verification at display time, so fac74c2f flips to Verified retroactively — no amend, rebase, or force-push, and the existing review anchors stay intact.
